A city councilor in southern France warns that some French citizens are gearing up for civil war as memberships of gun clubs explode in the aftermath of three massive terror attacks that have rocked the country.

In an article entitled What next? Could France be facing a civil war?, author Jonathan Miller, who is an elected council member in the village of Caux, asserts that the Nice truck attack has "shaken France to the brink of a terrifying escalation."

Warning that France "may be on the edge of something resembling a civil war," Miller reveals that membership in his local gun club has "quadrupled, from 200 to 800 members" in the last few months alone.

When asked why so many French people were buying guns and becoming interested in joining the gun club, one resident told Miller, "They're getting ready for a war."

"I talk to a lot of people at every level of French society and I am detecting a change of mood. And the mood is turning nasty," writes Miller, adding that he is "no longer taking for granted that they will put up with this much longer."

Miller explains that a lot of citizens are voting for right-wing politicians not because they are neo-fascists but because, "They are frightened" and nobody aside from people like Marine Le Pen have offered anything different to President Francois Hollande's feeble response to Charlie Hebdo, the Paris massacre, or the Nice atrocity.

Miller sums up a mood that was expressed again today after French Prime Minister Manuel Valls was booed by the crowd as he attended a memorial in Nice. Attendees chanted for his resignation after Valls controversially said that France must "learn to live" with terror attacks.

The council member is not the only prominent voice to warn of the potential for civil war in France.

As we reported last week, Patrick Calvar, who is the head of the Directorate General of Internal Security (DGSI), told members of a French parliamentary commission, "We are on the brink of civil war."

Speaking before the attack in Nice, Calvar said that one or two more jihadist terror attacks or a Cologne-style mass molestation incident could lead to a huge right-wing backlash.

As we highlighted last year, French security forces are also preparing for mass civil unrest and radicalized immigrants taking over entire neighborhoods, according to intelligence sources.
